This is how I did mine: Used a wire brush and took it down to bare metal, sprayed with Zinc Cromate primer, sanded with 400 grit sand paper, Sprayed my color, then shot it with a clear coat. Some will say to use a vinegar solution consisting of a 50/50 mix with water. I was told that after I had painted my boat. Good luck to you.PS This is probably going to be moved to the Boat section.
mjcombs, you'l probably get more replies in the boats forum instead of this forum. BUT, I'll tell you how i painted mine. I sandblasted the hull then primed it with a two part acid based primer that you can get at any autobody supply store. Just tell them what you are painting. Then you can shoot what ever color you want on it.
From my earlier post:Aluminum must be bare and all corrosion removed. (including seams...) use alumiprep, then alodine, dry, self etching zinc chromate, let cure for several days, then spray good high quality poly paint with hardner.If ya jus want a quickie cheap job: Cheap automotive enamel and use 3M pad to scuff up and paint two coats.
